Abstract

The interaction of (Ph 2PN)C(Ph)[N(SiMe 3) 2] with one equivalent of C 7H 8Cr(CO) 4 in diethyl ether gave cis-(CO) 4Cr[(Me 3SiN)C(Ph)(NHPPh 2)] in good yield. The compound has been fully characterized by analytical, spectroscopic and X-ray diffraction methods. The NH proton of the bidentate iminophosphine ligand undergoes facile deuterium exchange with D 2O at ambient temperature. A 1,3-silyl shift mechanism has been proposed for the formation of the product.
